on html and css versions:
What is wrong with using?
<!DOCTYPE html>
Sure it doesn't have a *real* DTD, but the W3C validator does
somehow validate pages that have this DOCTYPE declaration, right?
So, there must be some sort of *standards* it validates contents
against, right? Where/what is that "DTD"? I think that would be an
interesting thing to know.
You are missing two points.
First is that while browsers may not actually use the referenced DTD
(the http... clause), they do parse the HTML based on the DOCTYPE
html PUBLIC... clause and treat the HTML differently based on what
you declare.
Second is that just because the Validator approves of the supplied
HTML5 HTML, that does not mean that a browser will not choke on it or
display the code properly. This is not the case with pre-HTML5
DOCTYPES where if the Validator approves of the code, the browser
will correctly parse, interpret, and display it.
IOW: At the current time, <!DOCTYPE html> throws the browser into
"tag soup" mode where it tries to figure out what it is being
supplied with as opposed to knowing how to parse and handle it.
